Title: Extended zeolitic structures
Inventor: COLE EDWARD LAWRENCE
IPC: B01J29/70
Filed: 1969-07-05
Abstract: 1,245,349. Zeolite coatings. TEXACO DEVELOPMENT CORP. 5 July, 1969, No. 34005/69. Heading C1A. [Also in Divisions B1 and C5] An extended zeolitic structure is prepared by providing a support which is coated with a layer of hydrated alumina and which is of extended dimensions (i.e. having a length and geometric surface area substantially greater than the length and geometric surface area of discrete particles) and effecting reaction between alumina of the layer of hydrated alumina and a nutrient composition comprising a'source of silica and a source of an alkali metal oxide thereby to form, in situ, a crystalline aluminosilicate zeolite on (and possibly also in) the layer of hydrated alumina coated on the support. The reaction may be effected at a temperature of from 'ambient temperature to 600‹ F. for at least two hours. The source of silica may be silica hydrogel or silica hydrosol; the source of alkali metal oxide may be sodium hydroxide or potassium hydroxide; alternatively, sodium silicate may-be used both as the source of silica and as the source of alkali metal oxide. Alkaline earth metal apparently may be used in lieu of alkali metal. The nutrient composition, which may be in the form either of a paste or of asolution, additionally may contain a minor proportion of zeolite as seed and/or a minor proportion of alumina or alkali metal aluminate. The reactants preferably provide mole ratios of silica to alumina, alkali metal oxide to silica, and water to alkali metal oxide preferably between 1 to 1 and 25 to 1, between 0À1 to 1 and 5 to 1, and at least 10 to 1, respectively whereby philipsite, aralcite, chabazite, gmelinite, erionite, faujasite, mordenite, clinophlolite and zeolites A, B,C, E, F, H, J, K-G, M, Q, R, S, T, W, X, Y and Z may be formed. The zeolite formed may constitute 2'to 90 weight percent, of the combined alumina and zeolite content of the structure. The support may be in the form of bars, balls, chains, mesh, plates, saddles, sheets, strips, tubes or wire; exemplified materials from which the support may be formed are aluminium, steel, stainless steel, chrome steel, nickel, titanium, sintered metal materials and refractory and ceramic materials, for example glasses, magnesia, alumina, silica, other refractory metal oxides, silicates and carbides.

Title: Improvements in freewheel cycles and braking mechanism therefor
IPC: F16D41/36
Filed: 1929-11-08
Abstract: 342,773. Back-pedalling brake and free-wheel arrangements. PUGH, J. V., Meriden House, Meriden, Warwickshire. Nov. 8, 1929, No. 34153. [Class 136 (ii).] In a free-wheel cycle hub of the type in which the chain sprocket is internally toothed for engagement with helical projections on the hub and also on an adjacent rotatable member, so as to be traversed axially into driving engagement-with the hub when rotated in one direction and into engagement with the adjacent rotatable member when oppositely rotated (e.g. to expand a hub brake or to actuate a rim &c. brake through pawl and ratchet gear), the chain sprocket in moving from one engagement to the other passes through a zone where there is no positive rotary engagement. In the form shown in Figs. 1 and 5, the hub a is provided with a ring a<3> formed with a helicallyserrated region a<1> with which engage internal V-shaped helically-disposed teeth or serrations formed in the central aperture of a chain sprocket b. An outer ring-like member d, mounted on the hub spindle c adjacent to the back stay and adapted to actuate a brake, is formed with a similar helicallytoothed region on to which the sprocket b is traversed by back-pedalling. The toothed regions al, d<1> are conical and taper towards one another as shown, and their meeting portions may be further reduced in diameter as at a4, d<4>, Fig. 5, so that the sprocket b may ride or clatter over the central regions without positively engaging either member, the points of the internal sprocket teeth, however, being acted upon sufficiently to ensure the traversing movement. In the form shown in Fig. 10, the toothed regions on the hub ring j<1> and the adjacent rotatable member k are cut to a concave form, and the member k rotates against the frictional resistance of a spring n interposed between the member k and a disc m<2> on the cone m. In a further modification, the adjacent toothed regions are formed with parts of larger diameter constituting ridges tending to maintain the sprocket away from the intermediate clattering position until a deliberate driving or free-wheeling effort is applied.

Title: Lamp fitting
IPC: F21S8/02
Filed: 1964-08-21
Abstract: 1,066,999. Lamp fittings. GRœNZWEIG & HARTMANN A.G. Aug. 21, 1964 [Aug. 21, 1963], No. 34221/64. Heading F4R. A lamp housing is secured to a ceiling or wall structure and projects through an aperture in a false ceiling or wall which is composed of straight parallel strips spaced from the structure, the side faces of the housing being parallel to the longitudinal axes of the strips and each side face having at least one groove to receive the adjacent edge of the strip on that side of the housing. The grooves are arranged so that the strips on opposite sides of the housing may be disposed in the same plane or in stepped relationship. The width of the housing is a function of the width and spacing of the strips and the depth of the grooves so that the housing can be accommodated neatly in the space formed by cutting short one or more strips.
Patent GB-467176-A (GB)
Title: Improvements in and relating to rotary kilns
IPC: G05D23/27
Filed: 1935-12-10
Abstract: 467,176. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 10, 1935, No. 34227. Convention date, Dec. 12, 1934. [Class 38 (iv)] Temperature.-The temperature of materials being heated in an inclined, rotary kiln is maintained constant by varying the speed of rotation of the kiln in accordance with the temperature. The brushes of an A.C. motor driving the kiln are adjusted by a pilot motor 28 to vary the speed by the selective operation of two relays 64, 65 reversibly controlling the pilot motor according to the output of an amplifier 47 connected to a photo-electric cell trained on the heated material in the kiln and time-delay means control the periods of energization of the pilot motor. The amplifier comprises two thermionic valves 55, 56 the latter being conductive under normal temperature conditions. Thus of two relays 57, 59 the latter is energized and the relay 64 consequently holds its contacts open ; the contacts of the relay 65 are opened by gravity. A change of temperature causes the contact 73 or 75 to operate and actuate the pilot motor 28 to effect an appropriate change of kiln speed but the circuit of this motor includes contacts 82 controlled by a relay 81 in such a way as to limit the time during which the motor operates. The relays 64, 65 operate also contacts 77, 79 which energize a timing relay motor 84, a solenoid 83 and through contact 96 the relay 81. The solenoid 83 engages gears 105, 106 so that after a period a latch 108 is lifted by a member 107 resulting in the opening of contact 96. The circuit of motor 28 is thus broken at 82 but contact 110 causes energization of the elements 111, 117 of a similar timing device and the released element 98 opens a switch 86 to de-energize the motor 84. After another interval the contact 92 is opened and the solenoid 83 de-energized whereupon the relay 81 is again energized by the closing of contact 96, the latch 108 reengages and the cycle recommences, to continue so long as the contact 77 or 79 is closed, i.e. until the deviation of temperature in the kiln has been corrected. The speed of the kiln may be adjusted manually by switches 43 in an alternative circuit controlled by a switch 38. British Specification 456,795 and U.S.A. Specification 1,945,652 are referred to.

A clamping strap comprises a strip of metal of such a length that after being placed round the article to be gripped, its end portions overlap, a projection being provided adjacent the end of the underlying end portion, said projection engaging an aperture 14 in the overlying end portion when the two end portions are drawn together, characterized in that the projection consists of a rivet 12 loosely mounted in a bore 11, provided in the underlying and portion, said rivet having a lower rivet head 17 and an outwardly projecting upper rivet head 13 which engages the aperture in the overlying end portion when the two end portions are drawn together. The bore 11 may be of such size that the head 13 of the rivet can be passed through it or alternatively it can be smaller than the head which can be formed after the stem of the rivet is passed through the bore. Bores 4, 6 are also formed in each end of the strip, these bores being adapted to receive a tool by means of which the strap is tensioned round a hose pipe or the like until the aperture 14 engages the rivet. The tool is similar to a pair of pliers, the ends of the jaws being formed with annular grooves which engage the bores 4, 6. In a modification stamped up projections engageable by a flat-nosed tool are provided. One or more resilient arched portions 28, 29 may be formed in the strip so that a standard size can be provided which is adapted for use with articles of slightly variable diameter. When more than one such portion is provided, one is made more resilient than the other or others by providing the other or others with a rib 36. Such less resilient portions are made so that they overlie the opposite end of the strip.
